Miss Hepburn secured her place in the Diamond Classic when she finished fourth behind In A Wink in her heat last Tuesday week and has drawn barrier one for the $100,000 final.

De Campo, who will also drive the filly tomorrow night, said he wanted to give the daughter of Ultimate Machete her opportunity to lead.

"I think we give her every chance," De Campo told TABradio.

"These races don't come around every year.

"Her run in the heat was good.

"I should've popped to the breeze, and I would've run an easy second or won the race.

"I'll give her a chance in front, and I think she's a good top three chance from there."

Xceptional Arma and Water Lou, who won the other two Diamond Classic heats, head up the TABtouch market at $1.95 and $2.90 respectively.

Miss Hepburn was as much as $11 in betting but is now a $6 chance after De Campo indicated he wanted to lead.

De Campo won the Diamond Classic in 2014, where he drove the Jesse Moore-trained Tricky Styx to victory.

Prior to her Diamond Classic heat run, Miss Hepburn showed plenty of potential with a win and two placings in her first three starts.

One of her two placings was a fast-finishing second to Nase Vira in the Western Crown (1730m) in June.

De Campo said he was proud of how the filly had started her career.

"She just tries so hard," he said.

"Every time you ask for an effort, she just gives you more and more.

"That's not really common for a two-year-old filly."

The Capel trainer will also have a significant part to play in next Friday's Pearl Classic (2130m) for the colts and geldings, where he has Grevis and Menemsha qualified.

De Campo said he hoped Menemsha would finally get a good barrier draw.

"Menemsha hasn't been blessed with a barrier draw yet, so hopefully it comes next week for us," he said.

"On ability and what he does at home, I always said he was going to match it with those better ones.

"Hopefully he can show us when it matters."
